Cisco Email Security Appliance and Cisco Secure Email and Web Manager External Authentication Bypass Vulnerability

Cisco Email Security Appliance URL Filtering Denial of Service Vulnerability

Cisco Email Security Appliance and Cisco Secure Email and Web Manager Information Disclosure Vulnerability

A vulnerability in certain attachment detection mechanisms of Cisco Email Security Appliances (ESA) could allow an unauthenticated, remote attacker to bypass the filtering functionality of an affected system. The vulnerability is due to the improper detection of content within executable (EXE) files. An attacker could exploit this vulnerability by sending a customized EXE file that is not recognized and blocked by the ESA. A successful exploit could allow an attacker to send email messages that contain malicious executable files to unsuspecting users. Cisco Bug IDs: CSCvh03786.

Cisco AsyncOS on Email Security Appliance (ESA) devices through 9.7.0-125 allows remote attackers to bypass malware detection via a crafted attachment in an e-mail message, aka Bug ID CSCuz14932.

Cisco Email Security Appliance Content Filter Bypass Vulnerability

Cisco Email Security Appliance Denial Of Service Vulnerability

A vulnerability in Cisco AsyncOS Software for Cisco Email Security Appliance (ESA) could allow an unauthenticated remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper handling of certain TLS connections that are processed by an affected device. An attacker could exploit this vulnerability by establishing a large number of concurrent TLS connections to an affected device. A successful exploit could allow the attacker to cause the device to drop new TLS email messages that come from the associated email servers. Exploitation of this vulnerability does not cause the affected device to unexpectedly reload. The device will recover autonomously within a few hours of when the attack is halted or mitigated.

Cisco Email Security Appliance and Cisco Web Security Appliance Certificate Validation Vulnerability

A vulnerability in the Web UI and administrative CLI of the Cisco Secure Email Gateway (ESA) and Cisco Secure Email and Web Manager (SMA) could allow an authenticated remote attacker and or authenticated local attacker to escalate their privilege level and gain root access. The attacker has to have a valid user credential with at least a [[privilege of operator - validate actual name]]. The vulnerability is due to the processing of a specially crafted SNMP configuration file. An attacker could exploit this vulnerability by authenticating to the targeted device and uploading a specially crafted SNMP configuration file that when uploaded could allow for the execution of commands as root. An exploit could allow the attacker to gain root access on the device.

Cisco Email Security Appliance Shortened URL Denial of Service Vulnerability

Vulnerability in the CLI of Cisco Secure Email Gateway could allow an authenticated, remote attacker to execute arbitrary commands. These vulnerability is due to improper input validation in the CLI. An attacker could exploit this vulnerability by injecting operating system commands into a legitimate command. A successful exploit could allow the attacker to escape the restricted command prompt and execute arbitrary commands on the underlying operating system. To successfully exploit this vulnerability, an attacker would need valid Administrator credentials.

Cisco Email Security Appliance Information Disclosure Vulnerability

A vulnerability in Cisco Email Security Appliance (ESA) and Cisco Secure Email and Web Manager could allow an unauthenticated, remote attacker to conduct an HTTP response splitting attack. This vulnerability is due to the failure of the application or its environment to properly sanitize input values. An attacker could exploit this vulnerability by injecting malicious HTTP headers, controlling the response body, or splitting the response into multiple responses.
